ChatGPT and Codex training, on your teams' own cases
Has your organisation rolled out ChatGPT? Colombani.ai's Qualiopi-certified programmes run on it: half a day for executives, one day for business teams with ChatGPT agent mode and the Codex app. Exercises on your own cases, with the tool you have, by a trainer who uses it on client engagements every week.
In-house training, on-site or remote, for groups of three or more. Pricing by quotation, per group.
Colombani.ai offers two programmes deliverable on ChatGPT and Codex, Qualiopi-certified and eligible for OPCO funding. A half-day briefing for executives, with live demonstrations. A one-day "Working with AI agents" course for teams, using the ChatGPT app, its agent mode and the Codex app for tasks on files and folders. The trainer, Ulysse Trin, uses these tools on client engagements every week and publishes regularly on how they evolve.
One programme per audience, delivered on ChatGPT
Each programme is part of the Qualiopi catalogue and uses your own cases: your documents, your processes, your ChatGPT accounts. The materials and installation guide are those of the tool.
AI in business: executive briefing
What ChatGPT changes in your industry, demonstrated live on your own cases: finance, HR, sales, legal. The four market tools compared, the regulatory framework, the data questions, and a prioritised action plan to take away.
- ChatGPT and Projects
- Use cases by function
- AI Act and data
Working with AI agents
Your teams delegate repetitive tasks to ChatGPT: research, writing, reporting, document analysis with agent mode, tasks on files and folders with Codex. No coding. Everyone leaves with an agent configured for their role.
- ChatGPT, Projects and GPTs
- Agent mode and Codex
- Workflows by role
Training on the client's tool, to the same standard
Training exists so that teams work better on Monday morning, with the tool they actually have. When ChatGPT is deployed, Colombani.ai trains on ChatGPT and Codex, with materials specific to the tool, updated at every release, and exercises built on what ChatGPT and Codex actually do: Projects, GPTs, agent mode, tasks on files. What your teams learn, structuring a prompt, scoping an agent, checking a result, then applies to any other tool.
Advice remains independent of vendors. Colombani.ai uses ChatGPT and Codex on engagements, publishes an updated comparison of coding agents, and recommends a local or European model when confidentiality or sovereignty requires it. The "Local AI" course exists for that.

Ulysse Trin
Founder of Colombani.ai, Claude Certified Architect Foundations
Engineer (Epitech, MSc AI), certified by Anthropic on 22 April 2026. Consultant, trainer and developer: he works with Claude, ChatGPT and Codex, Le Chat and Copilot on client engagements every week, and the programmes teach what is built on engagements, and nothing else.
Do participants need a ChatGPT subscription?
Not for the executive briefing, as the trainer runs the demonstrations. For the team programme, each participant uses their own account with a ChatGPT Plus, Business or Enterprise plan. The plan is chosen with you before the session, depending on the data involved.
ChatGPT training or Claude training?
The one for the tool your teams will use. The skills taught apply to both. If nothing is deployed yet, the executive briefing compares the four market tools on your cases and the choice is made at the end, with the data and cost questions on the table.
Is the programme adapted to the tool or generic?
Adapted. The learning objectives and assessment are those of the programme in the Qualiopi catalogue, which secures the funding; the materials, the installation guide sent three days before and the exercises are those of the chosen tool, with its own features. One sequence compares the four market tools on confidentiality level, whichever one you use.
Can it be funded through the CPF?
No. Colombani.ai programmes are not listed for CPF funding. They are eligible for OPCO and FIF-PL funding through Qualiopi certification, covering the vast majority of employees and self-employed professionals in France.
Open enrolment or in-house training, on-site or remote?
In-house training, using your real cases and data, for groups of three or more. On-site in France or remote, as you prefer. An open-enrolment format is occasionally offered for the executive briefing.
